JAMES E. KELLENBERGBR, OF PENDLETN, OREGON, ASSIGNOR TO THE KELLENBERGER MANUFACTURING COME'ANY, OF SPOKANE, WASHINGTON, A CORPORATION.

AUTOMOBILE 'TRANSMISSION-ennemis.

Specification of Letters Patent.

Patented Nov. 20, 1917.

Application Ied February 21. 1916. Serial No. 79,780.

To all fwhom it may'conce'm.

Be it known that I, JAMES E. KELLEN'- nnnonu, a citizen of the United States, residU ing at Pendleton, in the county of Umatilla and State of Oregon, have invented certain new and useful Improvements in Automobile Transmission-Gearing'7 of which the following is a specification.

This invention relates to automobile transmission gearing and more especially one adapted for use on the Ford type of automobile.

The primary object of this invention residesI in the provision of means whereby the utilization of thc same will enable an operator of a Ford automobile to attain an intermediate speed between high and low gear.

another obiect of this invention resides in the provision of certain mechanical elements which can be readily attached to the present Ford transmission mechanism at a minimum expense.

A still further object of this invention resides in the provision of certain elements which when it is desired to assemble them upon FordY automobiles will readily be applicable thereto, withoutdestroying the initial function of its present power transmitting means. i Y

In the accompanying drawings; Figure 1 is a` vertical sectional view through the casingV which contains the supplemental power transmitting means` the same being shown as attached to the present universal joint and power shaft of the Ford automobile Fig. 2 is a transverse sectional view thereof on line 2-2 of Fig. 1;-Fig. 3 is a vertical sectional view through the casing of the supplemental power transmitting means showing the shiftable power gear as connected directly with the power shaft of the usual transmission geen-Fig. 4 is a vertical sectional view on line 4 4 of Fig. 3.

Referring to the present embodiment of this invention, the numeral 5 designates the transmission casing adopted in the construction of the Ford type of automobiles, but it is to be understood that the mechanism of this invention designated as a whole by the numeral 6 is readily applicable to other types of cars wherein the same functions will be from the present universal joint casing T thereof a suflicient distance. to permit its connection to the squared socket S of the power shaft 9 and the squared stud 10 of the universal joint 71.

To maintain the mechanism of this invention in a` rigid position. its casing 11 is secured at one end as at 12 to said transmission casing o and at its opposite end to the easing 7 of the universal joint as at 13.

Rotatably carried by said casing l1 is a supplemental power transmitting stub shaft 14 having a reduced angular stud 15 adapted to permanently engage the socket 8 of the power shaft .l and carrying thereon a fixed gear 16 to the rear of which is formed a series of lugs 17 for a purpose that will be hereinafter set forth.

Formed in said supplemental stub shaft 14 at the end opposite to that upon which the stud 15 is carried is a cylindrical socket 18, in which is rotatably engaged a cylindrical stud 19 of a second supplemental stub shaft 20.

This stub shaft 20 is rotatably suspended between the aforesaid first mentioned supplemental stub shaft 14 and the collar 21 of the casing 7 of the universal joint 71. Said collar 21 is provided with a cylindrical bushing 22. Mounted on the supplemental stub shaft 2O at that end opposite to the one carrying the cylindrical stud 19, is an angular socket Q3 adapted to permanently engage the angular stud 10 of the universal joint 71.

Rotatably carried by said casing 11 is a shaft 24 having fixed thereto a gear 25 which is adapted to permanently engage the aforesaid gear 16 of the supplemental stub shaft 14, while a second gear 26 of less diameter is carried thereby for engagement with the gear 27, which is slidably mounted on the squared portion of said supplemental stub shaft 20 and adapted to be moved into and out of engagement with said gear 2G by a lever designated by the numeral 2S.

Integrally formed upon that face of the gear 27 which is opposed to the gear 16, is a series of lugs 29 similar in construction to those carried by said gear 1G said lugs being adapted to engage to rotate the supplemental stub shafts 14 and 2O at the same speed when said gear 27 is moved out of engagement With the gear 26 and to the forward limit of its movement.

In order that this gear 27 may be readily moved upon thil supplemental stub shaft 2f), an annular groovil is formed in a` collar Iii vai-fied upon its rear face and is adapted to receive blocks 3'3 which are pivotally supported by the free ends of a yoke 33 carried by the lower extremity of said operating lover 25.

To attain the proper throw of the aforesaid levi-r, it is tule-ruined as at l to lugs 'Ii rari-led by the uwer IlS of the easing 11.

1With the above mechanism, it will be observed that the power from the present adopted transmission mechanism of the Ford automobile can either be imparted to vthe rear axle at the saine ratio et' speed attained hereefore or by releasing the direct connection between the stub shaft 1i() and the stub shaft fl and eonneeting then; through the. medium ot' gears fi, 26. 2li and lo, the transmission ean be changed to an intermediate speed.

l claim.

l. ln an automobile ehainge speed gearing, the combination oli' a power shaft, a driven shaft, stub shafts lixedly secured to the opposed ends olf said shafts, the stub shafts being rotatably engaged one with the other, a universal joint interposed between sei-tions oi said driven shalt. an annularly hanged honsing tor the power shaft, an annularliY tlanged housing 'for the univorsat l|`oint. a change speed gear set easing interposed between said housings and secured to the flanges thereof, means fior rotating said stub shafts in unison. and ine-ans 'for chunging the relative ratio oi speed ot' the saine.

2. In an automobile change speed gearing, the combination of an engine driven power shaft. a driven shaft. stub shafts fixedly secured to opposed ends of said Shafts, the

stub shafts being rotatably engaged one with the other, a universal joint for said driven shaft, an annularly flanged housing for the power shaft, an annularly flanged housing for the universal joint, a change speed gear casing interposed between said lnaisings and secured to the flanges thereof, bearings supported by said easing and said universal joint housing, said stub shafts being jonrnaled therein, means for rotating said stub shafts in unison, and means for changing the relative speed ratio of the same.

In an automobile change speed gearinr, the combination of an engine driven power shaft, a driven shaft, stub shafts fixedly secured to opposed ends of said shafts, the stub shafts being rotatably engaged one with the other, a universal joint t'or said driven shaft, an annularly flanged housing for the power shaft, an ani'iularly lianged housing tor the universal joint, a change speed gear set easing interposed between said housings and secured to the flanges thereof, bearings supported by said easing and said universal joint housing, said stub shafts being journaled therein, a fixed and a slidable gear carried by said stub shafts, a counter shaft mounted in said easing, gears carried thereby adapted to ed operate with said fixed and sldable gears, and nieans for shifting said siidable gear into loeked engagement with said lined gear and into toothed engagement with one ot said counter shaft gears, selectively.

In testimony whereof I afiiX my signature in the presence of two Witnesses.
